Boston Java Users ACM Chapter (formerly NEJUG)

Join us to learn how easy it is to prototype an AI Assistant, ChatBot or other GenAI project with the Oracle AI Microservices Sandbox – a free, open-source, zero-code tool for rapid experimentation and iteration. Use any LLM, any embedding model, any data, with the full power and security of Oracle Database 23ai AI Vector Search. Keep your sensitive data secure and control, costs with self-hosted models, measure the accuracy and performance of your project and optimize model choice, hyperparameter values, chunking and embedding strategies and more for your particular use case and corpus. Eliminate hallucination and knowledge cutoff. Easily compare performance of models. Experiment and optimize with confidence!

It's 2am Friday night, and you have a large software deployment in 5 hours. Suddenly, you receive alerts for your primary business application. The application is up, it's just not responding, and the user tickets are piling up. What's going wrong? How do you tell?

For situations like these, you need to have already captured the data that can help you quickly get a sense of the what's going wrong. Yet, many production environments have not enabled such data collection and some diagnostics have a performance cost that is unsuitable for many production applications. So, what is recommended and what can you do with the data you're allowed to collect?

In this session, we’ll look at some of the most commonly reported problems for Java applications, Java heap memory issues, and how to use low-cost data collection to diagnose those problems at first time failure.

Speaker:
Sandra Payne is the JVM Area Lead for Java Platform Group Support at Oracle. She began working with the Java SE Support team at Sun Microsystems in Burlington, MA, over 20 years ago and has spent the past several years specializing in JVM technology, diagnostics, and performance tuning. When not solving the world's JVM issues, you will lately find her cycling, traveling, or hanging out with her vibrant son, Sam.
